Causes

The exact cause of the condition is not known. Hormones made in the ovaries may make a woman's breasts feel swollen, lumpy, or painful before or during menstruation each month.

Up to half of women have this problem at some time during their life. It is most common between the ages of 20 and 45. It is rare in women after menopause, unless they are taking estrogen.

Symptoms

In most cases, symptoms get better after menopause. If you take birth control pills, you may have fewer symptoms. If you are on hormone therapy, you may have more symptoms.

Symptoms are more often worse right before your menstrual period. They tend to get better after your period starts.

Symptoms can include:

Pain or discomfort in both breasts

Pain that commonly comes and goes with the period, but may last through the whole month

Breasts that feel full, swollen, and heavy

Pain or discomfort under the arms

Thick or lumpy breasts

You may have a lump in the same area of the breast that becomes larger before each period and shrinks afterward. This type of lump moves when it is pushed with your fingers. It does not feel stuck or fixed to the tissue around it. This lump is common with fibrocystic breasts.

Exams and Tests

Your health care provider will examine you. This will include a breast exam. Tell your doctor or nurse if you have noticed any breast changes.

If you are over 40, ask your doctor or nurse how often you should have a

to screen for breast cancer. For women under 35, a may be used to look more closely at breast tissue.

You may need further tests if a lump was found during a breast exam or your mammogram result was abnormal. Another mammogram and breast ultrasound may be done.

Treatment

Women who have no symptoms or only mild symptoms do not need treatment.

Your health care provider may recommend the following self-care measures:

Take over-the-counter medicine such as acetaminophen or ibuprofen

Apply heat or ice on the breast

Wear a well-fitting or sports bra

Some women believe that eating less fat, caffeine, or chocolate helps with their symptoms. But there is no evidence that these measures help.

Vitamin E, thiamine, magnesium, and evening primrose oil are not harmful in most cases. Studies have not shown these to be helpful. Talk with your health care provider before taking any medicine or supplement.

For more severe symptoms, your health care provider may prescribe hormones, such as birth control pills or other medicine. Take the medicine exactly as instructed. Be sure to let your provider know if you have side effects from the medicine.

Surgery is never done to treat this condition.

Outlook (Prognosis)

If your breast exams and mammograms are normal, you do not need to worry about your symptoms. Fibrocystic breast changes do not increase your risk of breast cancer. Symptoms usually improve after menopause.
